Specification of Letters Patent.

Application filed January 15, 1908. Serial No. 410,945.

vBe it known'that I, JULn's A. DYBLIE, citizen of the United States, residing at Joliet` county of Will, and State of Illinois, have invented certain new and useful Im rovements in Tire-Pumps, of which the following is a specification, reference being had therein lo t 'e accompanying"drawing `Tliis invention relates to a tire pump, and particularly-to `a structure adapted to be driven from the moving part of a motor vehicle.'

The invention has for an object to provide anovel and improved construction of pump adapted to be held in the hands of the operator, and having a frame. withpivotal bearings at its opposite ends for the driving shaft and cylinder with an extension oisaid shaft for attachment or connection vn'th a moving part-#of the driving-'mechanism of-an auto- "A further objectof the invention is to provide an improved arrangement Vof inlet and out-let valves from the cylinder with a safety valve so arranged as to govern the pressure which may be applied to the tire from the pum Ot er and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the ap ended claims.

n the drawingz-Figure 1 is a lon 'tudinal section ofA the pump with arts in e evation;

Fig. 2 is a front elevation t ereof; and Fig. 8

is an enlarged section of the valved connections.

Like numerals refer tol like parts in the several views ofthe drawing.

The numeral 10 designates a frame or bar comprising the body of the um which is provided at each end with a ligandlb 11 to be grasped by the operator, and with the bearlng 12 for the cylinder at one end andthe bearing 13 forthe crank shaft at the op osite end thereof. The front piece 14 oi) this frame is plane, While the rear face thereof is provided with the strengthening rib 15 to im art the necessary rigidity to the parts.

ithin the bearing 12 the cylinder bearing 16 is disposed and provided With the flange 17 at one end abutting against the frame7 While the opposite end is retained in position by'fithe set nut .18".lsecured' `thereto. This bearing is provided lWith the cupped portion 19 adapted to receive the cylinder 2O extending longitudinally ofthe trame. The portion 19 is also provided with the valve cage 21 adapted tocarry a valve ofany desired character for instance, a ball valve 22, as shown in Fig. 1. The inner end of the cylinder 2() communicates with the passage 23 through the bearingl which passage terminates in ball valve, as shown.v Into .the end of this chamber 24 the hose connector 25 is secured by means of the threaded shank 26. One endof this connectorv is provided with the tubular member 27 over which the connecting hose extending to the tire to be inflated may be laced. This member is secured into one enfFof the connectorand into the opposite end thereof the safety valve 28 is secured, as shown in Fig. 3. This valve comprises the spring pressed stem 29 held closed under tension by the spring 30, and the tension of this spring is adjusted by means of the cap 31 t readed upon the exterior of the valve body 28, as shown. By this means the maximum pressure to be ap lied at any time may be governed and regu ated according to the conditions of use.

' At the opposite end of the frame from the cylinder connection the driving shaft 32' is mounted in the bearing 13 and held against lateral movement by the collark33 secured thereon. This shaft is provided with the crank arm 34 pivotally connected at 35 to the outer end of the piston rod 36 which at its opposite end carries the solid piston 37 within the cylinder 20. The driving shaft 32 is extended at its inner end 38 and may be provided With vany desired connecting means to engage the driven part of a motor vehicle so as to utilize the en e power thereof for the pumping action. the present illustration the pump is shown as applied to the construction of clutch ordinal" y used upon a machine such as the Cadillac automobile. This clutch is designated by dotted lines 39 and provided with a seat 40 with which a pin or other projection 41 upon the crank shaft is adapted to engage so that the rotation of the clutch member is transmitted to the driving shaft. When so applied the end of the bearing 13 may be rovided with a ferrule or collar 42 fitting t e hole' in the frame 'the valve chamber 24 which may contain the driving shaft of the pump. into clutched relation with a moving member of the automobile, Whilel the frame is held by the opposite handles after having been previously atv tached to the tire by the'usual tube or hose for that purpose. The pum ing action is thus effected by the power of the machine until a ressure is reached equal to that for which the safety valve has been set When this valve opens and allows the escape at which time the?? driving shaft can be Withdrawn from the clutch ofthe machine and the operation of the um immediately stopped.

It will be seen t at t e pump presents a simple structure occu ying but little room and which canbe'rea y handled and applied by the operator, ivhile the pivotal mounting of the cylinder and driving lshaft in line at oppositeends of the frame permit a rapid operation with the minimum of 'vibration so that the tool may be easily held in position. The invention therefore presents a simple, economically constructed and very efficient pump especially adapted for use in .connection with automobile tires and adapted to be driven from the mechanism thereof.
